SPECIFICATION forming part of Letters Patent no. 610,356, dated September 6,1568 Application. ma hl'ey 31,1898. Serlal No. 682,221.. (No model.)

To all whom it may concern.-

Be it known that we, THEODORE Y. KINNE and ALFRED GARTNER, citizens of the. United States,residing in Patcrsomcoun'ty of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Oompressible Tubes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such-as will enable othors skilled in the art to which it appertains to make and use. the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in compressible tubes or receptacles made of i mporvious ductile material and which are genorally used for paints, dentifrices, surgical dressings, dsc. Said tubes are usually provided with small discharge-outlets adapted to be closed by screw-threaded caps and having their opposite ends folded and pressed together or coiled and folded around a key or clamp for conveniently expunging the contents of said tubes. Various forms of clamps or keys for the last-mentioned purpose have been designed, but none of them rendered said folded ends of the tubes perfectly airtight. e

The object of our presentdnvention is to provide a cap for hermetically closing the flattened ends of the tubes and at the same time to act as means for progressively folding and compressing said tubes for the purpose ofdischarging their contents.

The invention consists in the improved compressible tubes, combining a cap or hood for hermetically closing Tandfolding the flattened end of said tube, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings,-

and Fig. 4 an enlarged detail perspective 5e view of the cap or hood used in connection with the tube.

In said drawings, (1. represents a cylindrical tube or receptacle, made of impervious ductile material and provided at one end with a small 5 5 discharge-outlet I), adapted to be engaged by a screw-threaded cap 0, all of the usual and well-known construction. The opposite end of said cylindrical tube or receptacle is pressed together or flattened, as at (1, Figs. 1 and 2, and is surmounted by and arranged within an elongated groove e of the cap or hood f,

which latter is provided at one end (or both ends) with a projection or handle g, as clearly illustrated in Fig. 4. Said cap or hood is se-.

eurely clamped upon the flattened end of the tube, with its members each side of the bend in laminated arrangement therewith,whereby a perfect air-tight joint is obtained. To prevent a reopening of said flattened end of the tube, the cap or hood is turned once or twice around, together with said flattened end, as gearly illustrated in the sectional view in ig. 3. portion bears against the inner surface of the top portion of the cap or hood.

When it is desired to expunge a portion of The extreme edge of the flattenedthe contents of the tube, the screw-threaded I 1. The combination of a compressible tube having means for closing one of its ends and having its other end flattened and compressed together, and a combined key and hermetical closure for the last-named end consisting of a metallic plate bent lengthwise upon itself toform substantially laminated members and clamped upon said end, and a handle integrally formed with and extending from one or both ends of oneof said members, substantially as described.

2. The combination of a compressible tube having means for closing one of its ends and having its other end flattened or compressed together, and a combined key and hermetical closure consisting of a metallic plate bent lengthwise upon itself and clamped upon, and having its members in laminated arrangement with, said compressed end of the tube, the edge of said compressed end being uniformly in substantial contact with the inside of said closure at the bend therein, and a handle integral with and projecting from one or both ends of one of said members, substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands this 13th day of May, .1898. V
